Hey mm34. I have been suffering the same thing and I cant get rid of it. It's been like 15-16 years for me. Never had bad breath and the day after I decide to give my girl at the time oral sex. I immediately noticed people calling me stank, and he smells bad. This has been a nightmare . Please tell me you figured out a cure?
I have bad breath and I noticed it the next day after I was with a girl and we had oral sex. SDT-s like throat gonorrhea ,chlamydia , was checked and there was a PCR test. Nothing was found, but I'm convinced that I caught something from that girl.
Never heard of a STD causing bad breeth. See your dentist for further info.
